ItemPatterns of surveillance for colorectal cancer: Experience from a single large tertiary institution(WILEY, 2021-08)AIM: Colorectal cancer surveillance is an essential part of care and should include clinical review and follow-up investigations. There is limited information regarding postoperative surveillance and survivorship care in the Australian context. This study investigated patterns of colorectal cancer surveillance at a large tertiary institution. METHODS: A retrospective review of hospital records was conducted for all patients treated with curative surgery between January 2012 and June 2017. Provision of clinical surveillance, colonoscopy, computed tomography (CT), and carcinoembryonic antigen (CEA) within 24 months postoperatively were recorded. Kaplan-Meier estimates were used to evaluate time-to-surveillance review and associated investigations. RESULTS: A total of 675 patients were included in the study. Median time to first postoperative clinical review was 20 days (95% confidence interval (CI), 18-21) with only 31% of patients having their first postoperative clinic review within 2 weeks. Median time to first CEA was 100 days (95% CI, 92-109), with 47% of patients having their CEA checked within the first 3 months, increasing to 68% at 6 months. Median time to first follow-up CT scan was 262 days (95% CI, 242-278) and for colonoscopy, 560 days (95% CI, 477-625). Poor uptake of surveillance testing was more prevalent in patients from older age groups, those with multiple comorbidities, and higher stage cancers. CONCLUSION: Colorectal cancer surveillance is multi-disciplinary and involves several parallel processes, many of which lead to inconsistent follow-up. Further prospective work is required to identify the reasons for variation in care and which aspects are most important to cancer patients.

ItemAnaemia and its impact on colorectal cancer patients: how can we better optimize surgical outcomes?(WILEY, 2021-05)BACKGROUND: Anaemia is a common manifestation of colorectal cancer (CRC). However, appropriate workup prior to surgery and the effect of anaemia on outcomes have not been well defined. This study aimed to describe preoperative anaemia incidence, investigations performed, treatment and associated complications in a CRC surgical population at a single large tertiary institution in Australia. METHODS: Patients who received surgery with curative intent for CRC between 2012 and 2017 were identified from a prospectively maintained database. Demographic and clinical outcome data were analysed. RESULTS: In total, 754 patients with CRC were included. Anaemia was found in 350 (46.4%) patients, of which 124 (35.4%) were microcytic, 20 (5.7%) were macrocytic and 206 (58.9%) were normocytic. Older patients were more likely to have anaemia (mean age 70.28 years, standard deviation (SD) 12.98 versus 64.74 years, SD 11.74). Only 89 patients (25.4%) were tested for iron deficiency, and of these, 76 (85.4%) were found to be iron deficient and 42 (47.7%) had low ferritin. Preoperative anaemia was associated with a higher incidence of postoperative complications (adjusted odds ratio (OR) 1.46, 95%, CI 1.04-2.05; P = 0.03) and a longer length of stay (LOS; average 1.8 days; 95% CI 0.3-3.3 days). CONCLUSION: A significant proportion of CRC patients had anaemia and the majority were normocytic. Only a small number of anaemic patients were tested for iron deficiency. Preoperative anaemia had an adverse effect on LOS and postoperative complications. The evaluation of anaemic patients is essential in CRC patients undergoing surgery.
